Hi All,Can anyone please help me with this?I have a client who has a Lavry Da924 and someone before him has heavily modified the power supply board.Could someone please help me identify the 4 requlators in the picture along with the power supply boar...

Well, the issue you are talking about is very complex. You have many components in your signal chain, that contribute to the noise and signal quality,not only in power supply,but also in the signal chain ckts. The USB A/D converters have their own po...

Part of the reason we call our computers 'transports' is to encourage people to think of the number-crunching part of an audio system in the same already familiar terms as a CD player - because all the same things matter: CD transports vary according...

This thread has been pretty interesting overall. I've read most of it and would at least like to provide some feedback on the technical side of designing with the 45 and 2A3 DHTs... at least from my personal experience. A few years back I decid...

decoud - thanks for the link, nice and minimalist,but as minimalism is no longer part of this project I need Unfortunately a more complex power supply.Romy -I'm building a full range amp. But...I need a small foot print so it will be high and relati...

Hi Alex,I am sorry, what you claim can not be. No cap is going to separate bass instruments better.The brilliance of the 834p circuit is that the EQ also uses the miller capacitance of the tubes in a very brilliant way. The power supply caps are very...

[quote user="steverino"] If the units are to be placed between the wall and the PP then I think that would be a safe way to use it. I do not recommend connecting audio equipment directly through them though.[/quote] That is kind of puzzling to me. Wh...

There of course is a ton of garbage on the net about the sound quality of a DAW with WLAN vs gigabit ethernet, analog or digital power supplies, memory, manufacturer of hard drive, active ports.I have primarily only really invested in lowest noise an...

[quote user="xandcg"]For power supplies, a possible quick solution would be to get a Komputer, but just the power supply and the box adapted for your board. Their (Lampizator) power supplies are reportedly to be very good. The price can always be neg...

DA, I would not use any switched power supply, not to mention that they do not need to be regulated for LEDs, relays and fans. I do not know if you build a full range Milq or more complicated multi-channel version. If it is a full range Milq with onl...

[quote user="PurePower"]Without its own source of power it would be impossible to truly isolate the PurePower output from the incoming utility power. That is why there is no difference in sound when the PurePwoer is on battery or it is on utility sup...

Yesterday my machinist informed me that the End of Life Phonostage’s chassis will be reedy next week. So, I desisted update the power supplies of the thing replacing the FRED diodes with those no reverse/forward recovery Silicon Carbide Schottky diod...

I designed up a steel chassis for both the Fullrange and DSET Melquiades. Here they are screwed together for the first time. Then I have made sure all the cutting and drilling has been in the correct places by quickly putting the parts in their pla...

I have a preference for making the power supply a certain way and using certain types of components. If I do that and am consistent about it, I can get better results from some of those old tubes than I can from the more recent types. But hearing one...

I continue to be amazed at the varied views relating to BAD power at certain times of the day.I broke with that 10 or more years ago in moving to amplifiers, line amps and DACs configured with switched mode supplies.I not only keep my DAC permanently...

CEC TL0 3.0 (I have CEC TL0 3.0 model 2018) is my favorite Transport and the question is could it be improved?
CEC has very very good dynamics good bass good pace good rhythm good dimension very accurate sound, low jitter and very tr...

The “Enjoy His Music” published the old celebrated by many DIYers Herb Reichert’s article about his 300B amp ideas.

If you follow this thread and my successes and tribulation with PurePower regenerators than you remember that I had problem with sound running two PP2000 for right and left channels. So, I had everything, including my DAW plugged into on PP2000,...

[quote user="cv"]Funny, I was just thinking about battery powering of amps... I know you have identified that the problem is more with the sources, but it would be interesting and quite feasible with the Melquiades and other components... wouldn...

Let us suppose that one manufacturer figures out what the grid is doing and how to solve it - in his own amps/preamps/DAC. Does that help us? Only if we happen to like their products...As the "high end" market is truly sick, the solution is always to...

dont know if the posters comment was meant to sound negitave or positive about this thread and you. myself and countless others who use PP2000 because its performance and clean power is what our hifi systems love. PP2000 is delivering the power and t...

The failure Herman had was probably on the input side - not the output. You will notice 2 things. 1. The system operated normally for 6 months, so it is unlikely an overload issue.2. The PurePower did its job of protecting the audio equipment (self s...

Sounds to me like your switch mode transformer is doing the buzzing. I recently purchased an APC product that charged the battery constantly, so long as it was plugged in. This caused quite a bit of heat and stench, from the hot switch mode power sup...

Well,I did speak with Damian in Technical Support at APS, and he informs me that this effect is something that they have reproduced in their lab, but only with extremely efficient loudspeakers and certain power supply designs in the amplifier. With ...

Depending on the UseCase, many things can influence the sound. Rectifiers, snubbers, impedance, corner frequency, speed, an inductor in series, regulation, isolation from the mains grid all are parameters to consider.I do not know of any really serio...

Hi Wellington and fellow Micro-Seiki fans,I will have to agree with your findings about the CU-180 as well. I have tried a stainless steel mat with similar results.I own two RX-5000's and cant't stress enough the rebuilding of the power supply with n...

[quote user="Paul S"]Anthony, it sounds like you have given a lot of thought to damping structural vibration. I was referring to the electro-magnetic fields thrown by transformers, and - based on my view of your perspective drawings - I was wonderi...

HiI'm now at a stage of building the chassis for full range Milq.It will be a two chassis,one power supply and one signal,very similar to Romys super Milq layout.The two will be connected by two separate cables AC and DC.A few questions please1.How a...

Paul, I know NOTHING about pentodes. I looked at the curves:at 1500V/300mA/-85V loaded with 3.2k will give a whooping 190Wwith +/-85Vmax swing, staying in A1. At 2.4k this drops to 155W.G2 @500V, eating 50mA of current(!)But the linearity...???? The ...
